Most upcoming 2014 BMW models will be available with the new iDrive Touch system, which features a touch sensitive controller knob for a whole new way of input. Instead of having to scroll for letter input, users can now write letters on the surface of the iDrive knob.
This new written input method can be used anywhere where a speller wheel is needed: navigation, multimedia search, contact search, phone numbers, etc.
It also accepts gestures for such actions as zooming in and out on a map.
Check out a demo below.
